[IT-25-99/E-B1]

ArmaSound Flooring sheet 25mm x 1m x 4m carton content 4 square metres.
High Performance Noise Reduction For A Quieter Environment.

25mm Sheets meet dynamic stiffness acc. to Building Regulation Part E

ArmaSound Floor is a lightweight, closed cell elastomeric foam that has been designed to act as an under screed resilient layer. Resilient layers acoustically isolate the concrete subfloor from the surface screed which is laid on top.

Laboratory assessment and continued pre-completion (PCT) testing, in accordance with ISO 140 and ISO 717, have proven ArmaSound to be a superior under screed resilient layer solution. At only 10mm thickness, the product comfortably surpasses the acoustic requirements of the Building Regulations.

Minimising noise transmission between floors in multi-storey buildings prevents unnecessary disturbance and conflict between neighbours, creating a more pleasant living and working environment for all. Acoustically treating floors is essential for compliance with Part E of the Building Regulations in England and Wales.

Each type of floor construction requires a different acoustic treatments. The most common floor construction, known as a "floating floor" construction, is a screeded concrete layer over decoupling insulation sheet laid directly on the structural slab. Satisfying the acoustic requirements in a floating floor construction requires a flexible, load bearing insulation such as ArmaSound Floor.
